Answer:
Yes, with change in humidity, enthalpy changes as well.
Explanation:
This can be explained by the given relation:
H =
where
H = enthalpy (in Btu/lb)
w = specific humidity (lb-water/lb-dry air)
= dry-bulb temperature (in )
The above relation clearly explains that if temperature does not vary, enthalpy is in direct proportion with the humidity.
So, any change in humidity results in a corresponding change in the enthalpy.
Answer:
1.7M
Explanation:
Given parameters:
Volume of solution = 0.3L
Number of moles = 0.5moles
Unknown:
Molarity = ?
Solution:
The molarity of a substance is the number of moles of solute that can be found in the volume of a solution.
Molarity =
Insert the parameters and solve;
Molarity = = 1.7M
Answer:The 2nd and 3rd one.
Explanation:
It has the same number of protons but different amount of nuetrons.
